The first flush accessory is designed to be installed at the top of your rainwater harvest tank to divert the initial amount of water away from your rainwater storage tank. As rain first begins to fall and run down a roof, it collects dust, pollen, dirt, etc. that can be detrimental to your rainwater stores. This product is designed to prevent a significant amount of those contaminants from entering your storage tank.
*This kit does not include an additional pipe to divert water away from the base of the tank. See the additional First Flush Connection Kit*
